IC REG BUCK 3.3V 2A 1.1MHZ TSOT23-6
Diodes Incorporated

Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardSynchronous buck converter with 3.8V to 32V input range and fixed 3.3V output at 2A continuous current. Integrates 125mΩ high-side and 68mΩ low-side MOSFETs for high efficiency. Features 1.1MHz switching frequency, Frequency Spread Spectrum (FSS) EMI reduction, ultra-low 22µA quiescent current, and supports Pulse Frequency Modulation for light-load efficiency up to 88% at 5mA. Suitable for distributed power supplies, consumer electronics, and embedded systems.
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
